Description

  The present invention generally relates to compounds useful as cyclin dependent kinase (cdk) inhibitors, pharmaceutical compositions containing them, and methods of formulating or using them for the treatment of cancer or proliferative diseases or other diseases , And intermediates and methods for making the same.

One of the most important and basic processes in biology is cell division caused by the cell cycle. This process reliably controls the generation of next generation cells with defined biological functions. It is a highly regulated phenomenon that responds to a variety of cellular signals from both intracellular and external sources. The complex network by which tumors promote and suppress gene production is an important component of this cellular signal process. Overexpression of tumor promoting elements or subsequent loss of tumor suppressor products will lead to unregulated cell growth and tumor generation (Pardee, Science 246: 603-608, 1989). Cyclin-dependent kinases play an important role in regulating cell cycle machinery. These complexes are composed of two elements: a catalytic subunit (kinase) and a regulatory subunit (cyclin). So far, nine kinase subunits (cyclin-dependent kinases 1 to 9) have been identified along with a plurality of regulatory subunits (cyclins A to H, K, N and T). Each kinase is associated with a specific regulatory partner and together creates an active catalytic moiety. Each transition phase of the cell cycle consists of a specific cyclin-dependent kinase complex: G11S with cyclin-dependent kinase 2 / cyclin E, cyclin-dependent kinase 4 / cyclin D1, and cyclin-dependent kinase 6 / cyclin D2; S / G2 by 2 / cyclin A and cyclin dependent kinase 1 / cyclin A; regulated by G2 / M by cyclin dependent kinase 1 / cyclin D. The coordinated activity of these kinases guides individual cells through the replication process and ensures the survival of each next generation (Sherr, Cell
73: 1059-1065, 1993; Draetta, Trends Biochem. Sci. 15: 378-382, 1990).

There is increasing evidence to show a relationship between tumor development and dysfunction associated with cyclin-dependent kinases. Cyclin-regulated protein and subsequent hyperactivity of kinases has been associated with multiple types of cancer (Jiang, Proc. Natl. Acad. Sci. USA 90: 9026-9030, 1993; Wang, Nature
343: 555-557, 1990). More recently, it has been found that endogenous, highly specific protein inhibitors of cyclin-dependent kinases have a profound effect on cell growth (Kamb et al., Science
264: 436-440, 1994; Beach, Nature 336: 701-704, 1993). These inhibitors include p16INK4 (inhibitor of cyclin dependent kinase 4 / Dl), p21CIP1 (general cyclin dependent kinase inhibitor), and p27KIP1 (specific cyclin dependent kinase 2 / E inhibitor) Can be given. Recent crystal structures of p27 bound to cyclin-dependent kinase 2 / A reveal how these proteins inhibit kinase activity through multiple interactions with cyclin-dependent kinase complexes. (Pavletich, Nature
382: 325-331, 1996). These proteins facilitate cell cycle regulation through specific interactions with the corresponding cyclin-dependent kinase complexes. Cells deficient in these inhibitors are prone to unregulated growth and tumor formation. Based on this series of evidence, many studies of small molecule inhibitors of the cdk family as therapeutic substances have been conducted.

  The present invention describes compounds that are potential inhibitors of a class of enzymes known as cyclin dependent kinases. The invention includes a therapeutically effective amount of at least a compound or compound of the invention, or an isomer, prodrug, tautomer, pharmaceutically acceptable salt, N-oxide, or stereoisomeric form thereof. Methods of treating cancer or other proliferative diseases are provided by administering one. The invention further provides a method of treating cancer or other proliferative diseases by administering a therapeutically effective combination of at least one of a compound of the invention and another anticancer or antiproliferative agent.

Assay 3: Clonogenic survival assay protocol using HCT-116 cells This assay was used to determine the concentration of compound that resulted in an irreversible loss of viability after a specific exposure period. In essence, the cells are exposed to the compound for 1, 2 or 5 days and then transferred to growth medium without the compound. After several days of incubation in growth medium without compound, the number of recovered colonies was counted as an estimate of the number of viable cells.

  The results of such a survival assay for the various compounds of the invention are shown in Table 3 (clonogenicity) as the concentration of compound (μM) that inhibits colony recovery by 50% (IC50).

Colonies were stained with crystal violet solution (0.4% crystal violet, 20% ethanol) for 5 minutes, washed twice with diluted water, and counted.

Assay 4: Use of Calcein AM Viability Assay for the Evaluation of Cdk Inhibitors in the Presence and Absence of Serum Proteins The potency of Cdk inhibitors measured by loss of cell viability was measured using calcein AM assay (Molecular
Probes). Calcein AM is a substrate for intracellular esterase and is cleaved only in viable cells to produce a fluorescent product that can be quantified using a fluorescent plate reader. The fluorescent signal is proportional to the number of cells that can be produced, and thus the loss of signal in response to exposure of the cells to the Cdk inhibitor. This assay can distinguish between cell cycle arrest and loss of viability where cells may still be alive, and is therefore well applied to the evaluation of Cdk inhibitors. Potentially cytotoxic compounds may cause significant loss of cell viability in such assays.

The IC ₅₀ of the cells was measured in the human colorectal cancer cell line HCT-116, normal human fibroblast IMR906. Proteins with adjusted IC ₅₀ were also measured in HCT-116.

The plate was incubated at 37 ° C. for 75 minutes (shielded) and the fluorescence signal was read on a fluorescence plate reader (excitation 485/20 and emission 530/25).

Assay 5: Blocked Cell Assay Cyclin-dependent kinase (Cdk) activity is required to promote cell progression through a well-defined stage of the cell division cycle. Proliferation of normal unconverted cells in culture requires the presence of growth factors, and when it is removed by serum deprivation, loss of Cdk activity occurs, resulting in cells being in a stationary stage G Entering ₀ ends the cell cycle. Thus, from a mechanistic point of view, Cdk inhibitors should have greatly reduced potency in cells arrested with respect to their cycle counterparts.

Inhibition of HCT-116 and IMR90 cell cycle arrest by serum starvation To confirm that the cells actually excited the cell cycle as soon as serum was removed, the percentage of BrdU positive cells showing cells that progressed through the S stage was Measured in the experiment. For the purposes of this experiment, cell viability was simultaneously assessed using SNARF-1, a fluorescent substrate for intracellular esterases that is active only in living cells. Together, assessment of BrdU incorporation and SNARF-1 cleavage by flow cytometry determined the viability of cells blocked on a single cell basis. For this analysis, cells were stained with SNARF-1 as described below, and then prepared for the measurement of BrdU incorporation as described above.

HCT-116 cells and IMR90 cells were plated in T25 flasks containing serum-containing media (RPMI-1640 or MEMα with 10% FCS, respectively) at the following concentrations: After 24 hours of growth, the medium was removed and the cells were washed and replaced with serum free medium.
HCT-116 + FCS 5,000 cells
HCT-116-FCS 100,000 cells
IMR90 + FCS 100,000 cells
IMR90-FCS 200,000 cells

Assay 7: HCT116 xenograft tumor model The agents, compounds of the present invention were synthesized in biodegradable excipients and prepared for intravenous administration. CPT-11 (Camptosar®, Pharmacia) was obtained as a pharmaceutical and prepared in 5% dextrose-water (D5W). All formulations were refreshed weekly and the injection volume was adjusted by body weight (0.2 ml / 20 g mouse).

Mice / Husbandry. Female nu / nu mice were obtained from Charles River, housed in static microisolators, and water and irradiated standard rodent diets appropriately (Purina Pico-Lab Rodent Diet).
20) gave.

  Measurement of maximum tolerated dose (MTD). Eight-week-old mice were divided into groups of 5 to 8 animals, and preliminary toxicity tests were conducted using unknown test compounds. Animals were treated with test compounds intravenously for 10 consecutive days and weighed twice weekly. Mice were frequently examined for clinical signs of any drug-related side effects. Acceptable toxicity to anticancer drugs in mice is defined by the NCI as having no average weight loss in groups greater than 20% and toxic death in treated animals being 10% or less.

Standard protocol: Athymic nude mice (male or female, 6-7 weeks old) were implanted subcutaneously with a single 1 mm ³ tumor fragment (tumor brie). Alternatively, cells derived from 5 to 10 × 10 ⁶ tissue cultures were transplanted to adjacent parts. Animals were monitored daily, initially twice a week, after which the tumors reached the desired size of about 100 mm ³ . When tumors grew to 62-221 mg at the calculated tumor weight, the animals were paired into appropriate experimental treatment groups (8-10 / group) and treatment with the test compound was initiated. Positive controls were dosed according to historical controls. Tumor weight was calculated and body weight was measured twice a week. The animals were frequently observed for drug side effects. The protocol requires that any animal with a tumor weight of 1000 mg be immediately euthanized.

  The length and width of the tumor were measured using a digital caliper, and the estimated tumor weight was calculated using the following formula.

Tumor weight (mg) = (w ² xl) / 2
In the formula, w represents the width (nm) of the HCT116 tumor, and l represents the length (nm) of the HCT116 tumor.

  Experimental treatment may cause partial regression (PR) or complete regression (CR) of the tumor. A PR is when the tumor size is less than 50% of the onset (Day 1) but not 0.0 mg for 3 consecutive days under study. On the other hand, CR is when no measurable tumor is observed for 3 consecutive days. The definition of healing is when the animal's tumor is reduced to 0 mg and maintained until the experiment is complete.

  Log cell kill (LCK) is a calculation to determine the percentage of tumor killed after the start of treatment and can be used as a quantitative measure of effect.

Log cell kill (LCK) = (TC) / (3.32) (Td)
Where T is the median time required for the treatment group mice to reach 1000 mg size, C is the median time required for the control group tumor to reach 1000 mg size, Td Is the tumor doubling time estimated from linear regression analysis of the semi-log growth plot of the control tumor during exponential growth, 3.32 to grow 1-log10 units, The number of doublings required for the population. Each LCK unit represents 1-log10 units of cell kill (eg, 1 LCK = 90% kill, 2LCK = 99% kill, etc.). A compound is considered active when the LCK value is> 1 (corresponding to> 90% tumor cell killing).

Tumor growth inhibition (TGI) is a calculated amount of tumor growth that is inhibited by treatment with a compound for a period of time. It is expressed as follows:
% TGI = 100 (1-T / C)
Where T is the median tumor size on a given day of the compound treatment group and C is the median tumor size of the vehicle control group on the same day.

  Toxic death is defined as death caused by treatment with a compound, not because the disease state has progressed. If the animal dies within one week after the last compound treatment and the tumor size has not reached 1000 mg, it is said to be toxic death. Non-tumor related deaths after this point are recorded but not considered toxic deaths.

  Tumor regression is defined according to the following convention: If tumor weight is reduced to <50% of starting weight (<50 mg), it is defined as partial regression (PR). If the tumor weight decreases below the measurable weight during the experimental period, it is defined as complete regression (CR). It is defined as healing when the animal becomes tumor-free at the end of the observation period.

To characterize the binding of Compound R to proteins, such as CDK2 / cyclin E, the purified protein fragment was diluted in a flowing buffer to obtain nine different protein concentrations. It was passed over the sensor surface continuously for 5 minutes and then through a buffer flowing for 5 minutes at the same flow rate. Binding and dissociation of the CDK2 / cyclin E complex to the surface of the CM5 Compound R-added chip was measured at a flow rate of 30 μl / min. After each experiment, insert the chip 3M
Reconstitution by injecting two consecutive injections of guanidinium-hydrochloride (20 seconds, 30 μl / min) followed by the next sample.

The data was analyzed using Bioevaluation software version 3.1 (Biacore AB, Uppsala, SE). The curve was normalized to the background obtained by the injection start and the control surface. The rate of binding and dissociation was determined separately or as a whole using the Langmuir 1: 1 binding model. Affinity (K _D ) was calculated using the formula: K _D = kdiss / kass.
